Abstract

The experimental conditions for the micro-scale argentimetric potentiometric titration of organic chlorides and bromides present in the same solution were investigated. Coprecipitation phenomena affect the titration but can be minimised by various means, thus making it possible to determine both halogens with an absolute error of less than 0.40%. For the mineralisation of organic compounds containing halogens a Schoniger flask, modified in order to allow an exact titration of small solution volumes, was used. The titrations were performed with an automatic apparatus.
